  A 32-bit RISC-V emulator in a shader (and C)

  List of scenes that I am particularly fond of:

  - Minecrat computer engineering: Culminated with this playable 3d simplified minecraft clone (CPU+GPU) https://www.youtube.com/watch?v=-BP7DhHTU-I

  - Shader computing scene: More of a subculture of an already marvelous subculture, people are finding weird ways to compute with shader

• RAVE

  9 1,397 6.6 Python

  Official implementation of the RAVE model: a Realtime Audio Variational autoEncoder

  I'm in the deep learning music scene, which is due for its stable diffusion moment in the next year or two. The (primarily) timbre transfer system called RAVE is where I'm starting, and my contribution is to optimize the system to improve training time.

• example-chrome-extension

  13 71 7.2 JavaScript

  Example Chrome Extension - open source examples for Chrome extension APIs

  

  Browser extensions. Not quite a website, not quite a mobile app, and surprisingly pervasive. Most people don't realize how incredibly powerful they are, even with manifest v3.

  I almost fell out of my chair when I found out there were no books on how to build them, so I wrote one: https://www.buildingbrowserextensions.com/ It was incredibly enjoyable to go through the APIs and write about all the different crazy things they can do.

  3,016 49,066 9.9 JavaScript

• neocities

  292 1,472 9.3 JavaScript

  Neocities.org - the web site. Yep, the backend is open source!

  

  * https://neocities.org

  I think the main focus of those communities is recapturing the spirit of the (arguably more fun) internet of the 90s to early 2000s. They're not specifically dedicated to static site minimalism, but there's definitely a large overlap.

• Speed-Run-Sidebar

  1 0 10.0 HTML

  A Display + Controller to integrate with OBS

  Speed running Mario Kart 64.

  I'm not great. I enjoy it though. It's also been a place to play around with small a programming project to make it easier to update my streaming UI. https://github.com/Forge36/Speed-Run-Sidebar

• FreePSXBoot

  37 627 0.0 C

  Exploit to allow loading arbitrary code on the PSX using only a memory card (no game needed)

  Most of the SDK has been tested and confirmed to be fully functional on real hardware, but there is some copy protection you will have to get around in order to run arbitrary software on a PS1. The traditional solution is to perform disc swapping or install a modchip, but nowadays we also have softmods [1] that make the process as easy as inserting a specially formatted memory card (which can be prepared using a PS2, or even a PS1 by swapping discs).

  You are not required to use CDs either. With the help of some code and linker script magic, you can build an image that can be booted directly from a cheat cartridge (or simply a parallel EEPROM) connected to the console's expansion bus, bypassing the copy protection checks entirely. There are also debugging tools that, once loaded, let you download an executable into RAM for quick testing and manage memory cards using a modified serial cable [2].

• new-wave

  1 1 10.0 Zig

  Stack Computer Bytecode Interpreters: The New Wave

  https://github.com/LAC-Tech/new-wave/blob/master/type.ml

  Looks like my last attempt failed when I got bogged down prototyping a type system in Ocaml then trying to port that to Zig.

  So in my case - it's not because I use them and they suck, it's because I find stuff like implementing type systems and GC very hard, and usually more practical things start wanting my attention more.

  Cellular Automata Machine (CAM6) Simulator

  I hate it when a program I wrote mocks me. In Lex Fridman's interview of Steven Wolfram, he demonstrates the machine learning functions in Mathematica by taking a photo of himself, which identifies him as a .... (I won't give it away):

  https://www.youtube.com/watch?v=ez773teNFYA&t=2h20m05s

  Here's a video I recently recorded of the CAM-6 simulator I implemented decades ago, and rewrote in JavaScript a few years ago.

  https://www.youtube.com/watch?v=LyLMHxRNuck

  I recorded that demo to show to Norman Margolus, who co-wrote the book and wrote the CAM6 PC Forth code and many rules, so it's pretty long and technical and starts out showing lots of code, but I'm sure you'll totally get and appreciate it. I linked to a pdf copy of the book in the comments, as well as the source code and playable app.

• lazybasic

  1 0 2.5 C

  A teeny, tiny BASIC interpreter

  I wrote a script that builds seamless background images out of sets of smaller images, kind of like contact sheets. This started for a comic book themed web site so that the background image could be a collage of comic covers with a special theme ( Christmas, celebration of a comic artist, ...etc. ) I am still cultivating the script so that it'll be friendly enough for public use. I'll place it on Github when that happens.

  I like to tinker with my own compilers / interpreters. I had read an article recently about someone building an example Linux shell and I wanted to try a couple of ideas where I thought I'd take a different approach than the author. I ended up building a very, very tiny BASIC interpreter in C. My proof that the interpreter was "good enough" was whether or not I could write a script in the dialect of BASIC to display the lyrics to the song "The Twelve Days of Christmas."

• op25

  8 333 9.1 C++

  Fork of osmocom OP25 by boatbod

  Using OP25[1] with RTL-SDR dongles to implement scanners for trunking P25 radio systems on a computer. And as a sidebar to that, listening in on geographically remote public safety radio systems using Broadcastify[2]. It's basically the old "radio scanner" culture, but taken online and distributed worldwide. People listen to all sorts of stuff, but given my background as a former firefighter and former 911 dispatcher, my main interest is listening to public safety dispatch stuff.

  That said, another commenter below mentioned modern "phreaking" and how it's become more radio centric... and while I won't admit to doing anything illegal, let's just say that there's some interesting stuff you can do / look at / listen to these days, especially with ubiquitous and inexpensive SDR hardware and related resources. See the recent story about the KrakenSDR passive radar stuff, and some of the papers that are out there about P25 security flaws, some of the automobile hacking stuff that's RF based, etc., etc. There's a fascinating world out there buzzing around on invisible electromagnetic fields... and you can tap into it with a $30 dongle and a Raspberry Pi (or your PC).

• gbs-control

  50 820 4.5 C

  - Sometimes the web UI won't have 1280x960 checked, even if it's outputting a 960p signal. I don't know if this is connected to the vertical shift bug, or if .

  Again I'd have to dig into the GBS-C source code to find out why mode changing behaves oddly. There will be a lot of learning to do, understand the software state and chip registers and how they correlate to profile settings and input/output behavior. I suppose I could file a bug at https://github.com/ramapcsx2/gbs-control/issues, but somehow I feel reluctant to do so, partly because I didn't fully understand the setup and don't know if many of these bugs wouldn't happen on a VGA CRT, partly just learned helplessness and not knowing if my bug report is detailed enough or will be ignored or attacked, partly because I'd prefer to chat with the developers in Discord/Matrix outside of a higher-stakes formal bug report or a forum I've never posted at before.

  >- Sites that work without JavaScript. Even better than the first, it's always a pleasure to see when a site is made properly for a change, without the toxicity of JavaScript that pervades the world wide web (WWW) as we know it.

  I kept the colors I used before, but dropped JavaScript and tried to use CSS that is compatible with multiple browsers. It has been a learning experience, but very interesting to see how far I can get to with just HTML and CSS.

  Now I've started focusing on semantic web tags, and accessibility testing. Much easier without JavaScript.
